Alfano Magnetic Receiver
This receiver typically gets mounted to the floor tray of your kart. It then picks up lap times by magnetic strips that are in the kart track. (not all tracks have these installed so you will need to check with your track) The receiver comes standard with all of the Alfano gauges.
This receiver is compatible with the Alfano Astro, Alfano Pro Plus, and the Alfano Pro V2. (this will not work with the old standard Alfano Pro)
